Crypto mining software linux grep
LoudMiner is an unusual case of a persistent cryptocurrency miner, distributed for macOS and Windows since August It comes bundled with pirated copies of VST software. The miner itself is based on XMRig Monero and uses a mining pool, thus it is impossible to retrace potential transactions. At the time of writing, there are VST-related applications 42 for Windows and 95 for macOS available on a single WordPress-based website with a domain registered on 24 August, The first application — Kontakt Native Instruments 5. The size of the apps makes it impractical to analyze them all, but it seems safe to assume they are all Trojanized.

25+ Linux Commands Raspberry Pi Users Need to Know
The cryptocurrency-miner, a multi-component threat comprised of different Perl and Bash scripts, miner binaries, the application hider Xhide, and a scanner tool, propagates by scanning vulnerable machines and brute-forcing primarily default credentials.
The threat also employs a process hider to conceal the miner binary, which makes a typical user more unlikely to notice the mining activity save for a drop in performance and suspicious network traffic. This method has been a known cover for threat actors that aim to scan, brute force, and mine. The attacker starts by gaining access to a machine through weak or default credentials. Then, a command will be run on the compromised machine:. The initial file min detected as Trojan.
UWEJS downloads another file min. UWEJS , which is the main shell script that installs the various components of this threat. After executing the main shell script, it will try to kill existing cryptocurrency-mining processes:. The shell script also downloads and executes the component file downloaders cron. UWEJT , which are executed daily by the hour and every 30 minutes respectively. These files drop rcmd. The shell script is also capable of downloading and extracting the miner archive monero.
UWEJS for the execution of its contents. The archive file contains the miner binaries, which can be executed by various shell and Perl scripts that are also contained in the file.
The contents of the archive file are primarily configuration files and those that execute various component files, such as config. The main shell script then proceeds to download and extract the scanner archive sslm. UWEJS for execution. The contents of the scanner archive include. The scanner would attempt to infect and gain control of devices in a private IP range It will try to infect all devices in the same local network as the host machine by brute forcing a list of credentials that contain 3, username and password combinations.
Based on the credentials used, the attack mostly targets servers related to databases, storages, gaming, and mining rigs.
If successful, the attacker will then be able to issue the aforementioned commands for cryptocurrency-mining. The threat actors behind this cryptocurrency-miner have utilized Haiduc and Xhide, known and old tools that have been notoriously used for various malicious activities. These tools, combined with brute-forced weak credentials, can persist in systems while operating under the radar of traditional network security solutions.
Such malware can also affect system performance and expose users to other forms of compromise. Users can also consider adopting security solutions that can provide protection from malicious bot-related activities through a cross-generational blend of threat defense techniques.

Ultimate Setup Guide for Cryptocurrency Mining with Linux & Nvidia Cards
I recently saw this interesting malware sample. The uploaded file is nothing more than a downloader for a cryptocoin miner. The downloader logo. After this it runs a series of cleanups to ensure that the system not running another instance of the miner. After it kills all of the running miner processes, it will start the downloader as you can see below. The code will first attempt to download the configuration file kworker. Note that it will try to do it both using wget and curl to ensure that it will work even if one of the tools is not available.
Ethereum(Crypto) Mining with Nvidia 3070(Ampere) on Ubuntu 20.04 with Renewable Energy
Your browser is obsolete! Back to news. Doctor Web recently discovered a miner that infects Linux devices. This malware can also infect other network devices and remove running anti-viruses. The Trojan, added to the Dr. Web virus databases as Linux. This malware consists of several components. When launched, the Trojan verifies that the server from which it will subsequently download other modules is available and searches on the disk for a folder with write permissions into which these modules are then loaded. After that, the script is moved to the previously selected folder named diskmanagerd and, using the utility nohup, is re-launched as a daemon. If no such utility exists in the system, the Trojan automatically downloads and installs the coreutils package which includes nohup.
Setting up a mining rig on linux
Recently, someone reached out to us about a malicious process they had discovered running on their web server. This process was maxing out the CPU, which is not unusual when a cryptominer process is running without any throttling. Below is an example of what this kind of process looks like when using the ps -aux command:. So, what creates this malicious process in the first place? The correct answer is a malicious, executable bash file that exists on the web server.

Dissecting the evolution of malware gives researchers insights into the knowledge of, and development processes used by, malware authors. Dota3, active in the wild, offers a unique opportunity to examine a strain of malware during what appears to be an intermediate stage between major versions. It was a simple device to allow the programmers to check if the machine was stocked, prior to them leaving their desks to retrieve a beverage. For how simple this device was, it was only a matter of time before computers became smaller and designers started incorporating these devices into more items as a matter of convenience. Like many innovations, ease of use, lower costs and convenience take precedence over security. In the last couple of decades, criminals have seized on this to make IoT devices work for their schemes.
